Dynamic check digit utilization via electronic tag

ABSTRACT

An exemplary system and method allowing for dynamic verification that cargo is being placed onto the correct carrier for transit is disclosed. The system may employ voice recognition to capture dynamically generated check digits from a display to verify the digits against a cargo record, thereby confirming that the cargo is being placed on the correct carrier. A voice enabled workflow allows a worker loading cargo to speak the last “n” digits on the identifying label of a piece of cargo to first uniquely identify the piece of cargo being handled. Once the cargo is identified, the system can direct the worker to the proper carrier into which the cargo should be placed. The worker then reads a unique “check digit” code generated on an electronic tag located in the carrier. The code is then verified by the system to confirm the carrier onto which the cargo was placed.

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the benefit of U.S. Provisional PatentApplication No. 62/097,097 for DYNAMIC CHECK DIGIT UTILIZATION VIAELECTRONIC TAG filed Dec. 28, 2014. The foregoing patent application ishereby incorporated by reference in its entirety.

FIELD

Embodiments of the present invention generally relate to the field oflogistics management and, more specifically, to a system that allowsvoice confirmation of a dynamic check digit code to verify that a parcelis being sorted, routed, and delivered properly.

BACKGROUND

When sorted and prepared for delivery, packages (i.e., cargo, parcels,containers, crates, etc.) are typically classified based upon thespecific delivery location for the package, assigned to a deliveryroute, and loaded onto a delivery vehicle either by a sorter or by adelivery driver. Carriers that deliver packages, or that load and sortcargo, need a real-time solution to confirm that the cargo or parcelsbeing sorted are routed correctly. This process requires verificationthat the cargo is being placed in a given transit carrier delivery truckin order to confirm that the cargo is on the correct carrier (e.g., thatthe cargo is following the scheduled route, that the associated routestops that will carry the cargo to the correct destination, etc.).

Although a worker can scan a bar code inside the truck for each packagethat is placed therein, this solution requires that the worker stop andfree up a hand to operate the scanner in order to scan both the cargoand the barcode in the transit vehicle. This negatively impacts theergonomics and labor costs associated with requiring a hands-busy workerto alter their progress and work flow in order to complete the scanningprocess for each piece of cargo. The requirement that a worker handle ascanner and serially scan the cargo in order for the carrier to confirmrouting can be cost prohibitive.

Therefore, a need exists for improved cargo tracking processes,including but not limited to a hands-free system for confirming therouting information for a package.

SUMMARY

The present disclosure relates to a method and system allowing fordynamic verification that cargo is being placed onto the correct carrier(e.g., the correct delivery truck or other delivery vehicle) for transitalong the proper routing. The system employs voice recognition tocapture dynamically generated check digits from an electronic tag—an“eTag” display—to verify the check digits against a cargo recorddatabase thereby confirming that the cargo is being placed on thecorrect carrier.

The present disclosure provides for the use of a voice enabled workflowwherein a traditional barcode scanner may be replaced with a voicerecognition system. A worker loading cargo speaks the last “n” digits onthe identifying label of a piece of cargo to first uniquely identify thepiece of cargo being handled. This information is transmitted to aserver. Once the cargo is identified and located in the shippingmanifest by the server, the system directs the worker to the propercarrier into which the cargo should be placed.

In traditional methods, when the worker placed the cargo into thecarrier the worker utilized a barcode scanner to scan both the cargo anda tag in the carrier. This information was utilized by the system toconfirm correct placement. In the present disclosure, instead ofscanning the cargo and the carrier, the worker reads a unique “checkdigit” code generated on an eTag display located in the carrier. Theunique code is then verified by the system to confirm the carrier ontowhich the cargo was placed.

The present disclosure may include use of ID digits on the cargo and avoice recognition system to capture the ID digits, as well as theconcept of dynamically generated “check digit” codes on the eTags withinthe carrier. This process makes the unique value completely dynamic foreach and every worker interaction as opposed to either completely staticwith paper labels, or slightly variable by using a predetermined list ofpermutations based on a label with a matrix of values.

In one embodiment, the system utilizes a random number generator so thateach interaction uses a different number over a programmable period oftime. This solution prevents a common problem known as “check digitmemorization” where voice workers visit the same locations often enoughthat they know and can speak the check digit value before reaching thecorrect location.

Further, the eTags may be mounted inside each carrier in a way that theycan only be viewed by the worker when they are extremely close to thecargo bay of the carrier so that there is no chance of reading thecorrect check digit value while also putting the parcel on the wrongcarrier.

In an alternate implementation, a predetermined synchronization betweenthe application and the eTag can be implemented to reduce the cost andthe power requirements of the electronic tag.

The foregoing illustrative summary, as well as other exemplaryobjectives and/or advantages of the invention, and the manner in whichthe same are accomplished, are further explained within the followingdetailed description and its accompanying drawings.

DETAILED DESCRIPTION

Referring now to the drawings (FIGS. 1-3), a method and system thatallows dynamic verification that cargo is being placed onto the correctcarrier for transit along the proper routing is shown and illustrated.The system can employ voice recognition to capture dynamically generatedcheck digits from a display to verify the generated digits against acargo record database, thereby confirming that the cargo is being placedon the correct carrier.

The operation and interaction of the voice recognition system, and thewireless communication between the application server and the headsets,is known in the art and will not be discussed in detail herein.Additionally, the overall package workflow and database systems thatenable high volume package routing are also known, and will not bediscussed in detail.

As set forth above and shown schematically at FIG. 1, the presentdisclosure provides for the use of a voice enabled workflow wherein atraditional barcode scanner (or other data entry device) may be replacedwith a voice recognition system 10 that may be contained on a server. Intradition systems, a worker had to handle a scanner to determine wherecargo was being routed and to verify placement of the cargo at thecorrect carrier location. When the worker placed the cargo into thecarrier, the worker would scan both the cargo and a tag in the carrieragain in order to update the system. This required that the workerfrequently interrupt their workflow in order to pick up and utilize thescanner.

In the exemplary system, a worker 12 loading cargo 14 speaks the last“n” digits 16 (e.g., 123) on the identifying label 18 of a piece ofcargo 14. A headset 20 or other speech enabled device transmits thespoken last “n” digits 16 to the voice recognition system 10 to uniquelyidentify the piece of cargo 14 that the worker is handling. Once thecargo 14 is identified, the system 10 locates and verifies the cargo 14against a cargo record database and directs the worker 12 to the propercarrier 22 into which the cargo 14 should be placed (e.g., “Place thePackage in Carrier ABC”).

In the exemplary system, instead of scanning the cargo 14 and a tag inthe carrier 22 as was done in traditional systems, the worker 20 reads aunique “check digit” code 24 generated on an electronic tag “eTag” 26located in the carrier 22. The eTag 26 may be a simple wireless devicewith a display (e.g., LCD, e-ink, etc.). The code 24 is then transmittedto the system 10 and verified by the system to confirm the carrier 22onto which the cargo 14 was placed. FIG. 3 is a simplified flow chart ofthe basic system operation as generally described herein.

As set forth herein, the exemplary system makes novel use of the voicerecognition system to capture the cargo ID digits as well as the conceptof dynamically generated “check digit” codes from the eTags within thecarrier, making the unique combination of values completely dynamic foreach and every worker interaction as opposed to either completely staticwith paper labels, or slightly variable by using a predetermined list ofpermutations based on a label with a matrix of values.

In one embodiment, the system may utilize a random number generator sothat each interaction uses a different number over a programmable periodof time. This solution prevents a common problem known as “check digitmemorization” where voice workers visit the same locations often enoughthat they know and can speak the check digit value before reaching thecorrect location.

Further, the eTags may be mounted inside each carrier in a way that theeTags can only be viewed by the worker when the worker is extremelyclose to the cargo bay of the carrier so that there is no chance ofreading the correct check digit value while also putting the parcel onthe wrong carrier.

In another implementation, a predetermined synchronization between theapplication and the electronic tag can be implemented to reduce the costand the power requirements of the electronic tag. In this case, thesystem server 10 may periodically generate the “check digit” and provideit to the eTag or, vice versa, the eTag may periodically generate the“check digit” on a predetermined schedule and synchronize it with theserver 10. Wireless interaction between the headset 20, voicerecognition system/server 10, and the eTag 26 is generally shown at FIG.2.

While the exemplary system is illustrated in the context of a wirelessheadset, the system anticipates implementation via wireless headsets,wired headsets, worker mounted integrated voice recognition and handsfree scanner devices, vehicle mounted voice recognition computingdevices, and mobile worker workstations (among other configurations).These various devices may be integrated through flexible connectivity ofdevices and servers that facilitates the transfer of information beyondthe traditional capabilities of voice software. This connectivityprovides the launching point for implementing voice-enabled operationsto achieve the highest levels of productivity, extendible architectureand the seamless voice-enablement of tasks and workflow execution.

While there is shown and described herein certain specific structuresembodying a system that employs voice recognition to capture dynamicallygenerated check digits from a display to verify them against a cargorecord thereby confirming that the cargo is being placed on the correctcarrier, it will be manifest to those skilled in the art that variousmodifications and rearrangements of the parts may be made withoutdeparting from the spirit and scope of the underlying inventive conceptand that the same is not limited to the particular forms herein shownand described except insofar as indicated by the scope of the appendedclaims.
